A work can be completed by 18 boys in 24 days. If 6 boys leave after working for 12 days, then how many days will be needed to complete the remaining work?
18 boys can complete the work in 24 days.
=> Total work = $$18\times24=432$$ MD (mandays)
Now, 6 boys leave after working for 12 days, => Work done in these 12 days = $$18\times12=216$$ MD
Remaining work = $$432-216=216$$ MD
After 6 boys left, work done per day will be $$12$$ MD
=> Time taken = $$\frac{216}{12}=18$$ days
